The combat is not fun, and frankly seems completely out of place. The enemies have no attack telegraphs, the floaty controls make it very frustrating to dodge their bullets, there's no way to replenish health, and death means restarting from the title screen. As a result, I don't think I even got to the "out of control" part. The one mechanic I found kind of interesting was that you need to platform on enemy corpses.
Oh, and enemies can shoot through enemy corpses, but the player cannot. This got me into one situation where I was forced into a game over as I only had a couple lives left, there was a corpse in front of me under a long roof, and on the other side of the roof was an enemy. I had no choice but to push the corpse all the way to the other side so I could jump over it and kill the enemy that was shooting me the entire time.
If the player could aim using the mouse, instead of only shooting horizontally, I think combat would have felt a lot more possible, and maybe even fun.
